Retrying behavior for Guzzle

Installation

Add dependency mikeevstropov/guzzle

$ composer require mikeevstropov/guzzle

New options

• requests_limit

  Accepts:

  • integer - positive integer

  Default:

  • 1 - only one attempt

  Maximum number of attempts to receive a response.

• repeat_on

  Accepts:

  • array - array with a numeric index

  Default:

  • array(0, 5) - repeat failed request or if response code is 5xx

  List of error codes for retrying requests:

  • array(5) - on GuzzleHttp\Exception\ServerException (5xx code)
  • array(4) - on GuzzleHttp\Exception\ClientException (4xx code)
  • array(0) - other TransferException like GuzzleHttp\Exception\ConnectException

  You can combine it like array(4, 5).

Usage

<?php

$client = new \GuzzleHttp\Client();

// Let's try to request "http://httpstat.us/503" that
// page will always return "503 Service Unavailable"
$response = $client->get('http://httpstat.us/503', [
    'requests_limit' => 3,
]); // will thrown GuzzleHttp\Exception\ServerException after 3 attempts

// We can pass option "repeat_on" to prevent retrying
// if response has code 5xx (by default [0, 5])
$response = $client->get('http://httpstat.us/503', [
    'requests_limit' => 3,
    'repeat_on' => array(0, 4)
]); // will thrown GuzzleHttp\Exception\ServerException after first request

// But same options with request to the page that return 4xx
// will have 3 attempts, because we pass "4" as array item in
// option "repeat_on"
$response = $client->get('http://httpstat.us/402', [
    'requests_limit' => 3,
    'repeat_on' => array(0, 4)
]); // will thrown GuzzleHttp\Exception\ServerException after 3 attempts
